What is filament winding process?
Filament winding is a fabrication technique mainly used for manufacturing open (cylinders) or closed end structures (pressure vessels or tanks). This process involves winding filaments under tension over a rotating mandrel. Once the resin has cured, the mandrel is removed or extracted, leaving the hollow final product.
What are some typical products that are made by filament winding?
Some modern products created using composite filament winding
- Golf club shafts.
- Automobile drive shafts.
- Sailboat masts.
- Oars and paddles for small boats.
- Small aircraft fuselages.
- Spacecraft structures.
- Pressure vessels like firefighter oxygen bottles.
What is the use of winding machine?
A winding machine or winder is a machine for wrapping string, twine, cord, thread, yarn, rope, wire, ribbon, tape, etc. onto a spool, bobbin, reel, etc.
What fiber reinforcements are involved in filament winding?
The most commonly used reinforcements are carbon, graphite, glass, and thermoplastic fibers. Reinforcement fibers are combined with polymer matrix in various ways: bag molding process, compression molding, pultrusion, filament winding, resin transfer molding, and injection molding.
What are the types of filament winding pattern?
Basically, three types of winding patterns: circumferential, helical, and polar winding.
What are the advantages of filament winding?
A big advantage of filament winding is that it used continuous fibres which leads to very good material properties for both strength and stiffness. There is also the ability to orientate fibre direction for ‘optimised’ composites.
Is filament winding possible in thermoplastic composites?
Thermoplastic filament winding offers the possibility to build up continuous fiber reinforced lay-ups with well-defined fiber orientation and accurate positioning of the fibers.
What are the types of winding machine?
Types of Winding Machines

How many types of winding machines are there?
There are two types of winding machines to wind the yarn in cone or cheese form. These are: drum winding machines. precision winding machines.
Why filament winding is required?
Filament winding results in a high degree of fiber loading, which provides high tensile strength in the manufacture of hollow, generally cylindrical products such as chemical and fuel storage tanks, pipes, stacks, pressure vessels, and rocket motor cases.
What are prepregs used for?
Prepregs are typically used by experienced fabricators who are interested in minimizing the weight of their part. Typical applications include aerospace, racing, sporting goods, pressure vessels, and commercial products. Generally, prepregs are used by fabricators who have experience with hand layup and vacuum bagging.
What is a winding pattern?
Basically, three types of winding patterns: circumferential, helical, and polar winding. The three winding patterns diagram are shown in Figure 4. The circumferential winding is a high helical winding angle that approaches almost 90 degrees. …
Can a manual lathe machine be converted into a 4-axis filament winding machine?
Preprints and early-stage research may not have been peer reviewed yet. The objective of the project was to study the potentiality of converting the manual lathe machine into a 4-axis filament winding machine. Filament winding is an automated process for manufacturing the advanced reinforced composite structural components.
Why is the cost of a 4-axis filament winding machine so high?
Usually, the price of a 4-axis filament winding machine is very high due to the high priced & complex control system. Since the filament winding machine works machine is a better option in terms of cost as well as customization.
How to control tension in filament winding machine?
